TWISTED ISM.

Application filed April 21, 1981.- Serial No. 531,797.

This invention relates to a twister mechanism designed primarily for use in connection with spinning machines for twisting yarns to produce thread, but it is to be understood that a twister mechanism in accordance with this invention may be employed in any.

Further objects of the invention are to ro-' vide, in a manner as hereinafter set fort a mechanism for the purpose referred to which is simple in its construction and arrangement, strong, durable, compact, thoroughly eflicient in its use, readily installed with respect to a spinning machine, operated from the driving shaft of the spools of a spinning machine, producing a uniform thread, expeditiously repaired when occasion requires, and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arran ement of parts as hereinafter more speci cally described, and illustrated in the accompanying drawin s, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope corresponding parts from each end of the 'roll 2 is a pintle 4. The roll 2 centrally thereof has an annular peripheral groove'5 of concave cross section.

The plntles 4 of head 1 are revolubly mounted in diametrically opposed cutouts or grooves 5 formed in the flanged upper end of a vertically disposed hollow rotatable twister shaft 6. The head 1 is revolved on its longitudinal axis as the thread 7 is formed and as the-thread 7 travels towards a revoluble holder therefor. The holder is indicated at 8. Thehead 1 also revolves h0rizontally on a vertical axis, as it is carried with the shaft 6 and this movement of the head and shaft twists the yarns 9 as they are fed from the spools of the spinning machine.

The twister mechanism also includes a supporting plate 10 provided in its upper. face with a pair of spaced opposed bearings 11 in which isjournaled the operating shaft of the mechanism and such shaft is indicated at 12 and is provided with a worm 13. The shaft 12 is connected in a suitable manner to the, shaft of the spools of the spinning'machine. The connection is not shown but preferably 1t W111 be by gear arrangement. The plate 10 is also formed with an opening 14 through which extends the shouldered hub 15 of a stationary gear 16. The hub 15 is fixedly secured to plate 10 and projects above the upper face thereof. The flange at the upper end of shaft 6 is indicated at 17 and abutting thereagainst is a Worm gear 18 which seats upon .the top of the hub 15. The gear 18 is fixed to the shaft 6 and is driven from the worm 13thereby providing for the operation of the twister shaft 6.

The shaft 6 depends below the gear 15 and has fixedly secured to its lower end a turn table 19 which has securedto its lower face two pair'of straps and each strap has its inner end formed with a bearing. The straps of one pair are indicated at 20, 21 and the straps of the other pair at 22, 23. The strap 20 opposes the strap 22 in spaced relation and the strap 21 opposes the strap 23 in spaced relation. The bearings at the inner ends of the straps 20, 21, 22 and 23 are indicated respectively at 24, 25, 26 and 27. Each of the straps. is of angle shaped cross sectionforming a horizontally disposed arm 28 and aver-tically disposed arm 29. The bearings are formed on the vertically disposed arm of the straps. Holdfast means 30 are rovided for securing the straps to the turn table 19. The straps are slotted as at 31 whereby the straps of one air can be adjusted relative to the straps o the other pair.

Journaled'in the bearings 24, 25 is a shaft 32 provided with a rubber roller 33. Journaled in the bearings26, 27 is a shaft 34 1'0- vided with a rubber roller 35. The sha 34 is extended from the bearing 27 and carries on its projecting end a beveled gear 36, which meshes with a beveled gear 37 carried on the lower end of a shaft 38 which extends up through the turn table 19 and carries a bevel gear 39 permanently meshin with the fixed gear 16. The shaft 6 provi es a passage 38 for the thread as it passes oif head 1 and travels in a direction toward the rollers 33, 35.

z The function of the rollers 33, 35 is to ull the thread 7 across the head 1. The sha 12 is operated at the same speed as the spools of the spinning machine. The worm ear 18 revolves in the direction of the arrow igure 1. The turn table 19 turns in the direction of the arrow Figure 1. The gears 37 39 turn in the direction of the arrows Figure 1. The rollers 33, 35 turn in the direction of the arrows Figure 3.

The yarns 9 are fed from the spools on the spinning machine and after the yarns are twisted into a thread, the latter is looped around head 1, passes through shaft 6 and between rollers 33, 35, and is then wound upon the holder 8, the latter being operated in the desired manner and by any suitable means. The holder 8 is flanged at each end as at 8' and said holder is in the form of a spool.

What I claim is 1. A twister mechanism comprising a hollow, rotatable twister shaft providing a thread passage, operating means for the shaft, a revoluble yarn twister roll mounted in the upper end of and bodily carried with said shaft for twisting the yarns into a thread and for winding and unwinding successive lengths of the thread thereon and thereof, a turn table bodily carried by said shaft, opposed rotatable rollers carried by said turn table for pulling the thread from off said roll, driving means for said pulling rollers connected to the turn table, means for operating said driving means, and said roll provided with a peripheral .groove of concave cross section.

2. A twister mechanism comprising a hollow, rotatable twister shaft providing a thread passage, operating means for the shaft, a revoluble yarn twister roll mounted in the upper end of and bodily carried with said shaft for twisting the yarns into a thread and for winding and unwinding successive lengths of the thread thereon and thereof, a turn table bodily carried b said shaft, 0 posed rotatable rollers carrie by said turn ta e for pulling the thread from off said roll, driving means for said pulling rollers-connected to the turn table, means for operat' said drivmg means, a combined thread winding and holding means ar'ran edbelow said rollers, and said roll provitf groove of concave cross section.

3. A twister mechanism compris' a hollow, rotatable twister shaft providing a thread passage, operating means for the shaft, a revoluble yarn twister roll mounted m the uptper end of and bodily carried with said sha for twisting the yarns into a thread and for winding an unwinding successive lengths of the thread thereon and thereof, a turn table bodily carried by said shaft, opposed rotatable rollers carried by said turn table for pulling the thread from off said roll, driving means for said pulling rollers connected to the turn table means for operating said driving means, said roll provided with a peripheral groove of concave cross section, and means for adjusting said rollers relatively to each other.
